The purpose is to develop an iPhone Application to be used by the company employees for

scanning and managing their RFID tags for their job tasks. Using the application the users will

be able to connect to the job tasks from a centrally managed database and will be updating it

with their assigned tasks status.

Client Requirement

Project Challenges

Team faced the following challenges:

Developing an application on iPhone platform to be used by the company employees

for scanning and managing their RFID tags for their job tasks.

Using the application the users will be able to connect to the job tasks from a

centrally managed database and will be updating it with their assigned tasks status.

Integrating iCarte mobile SDK to scan RFID.

Implementing UI of the application for different screens accordingly.

Implementing and managing local DB as well as on server using sync feature.

Capture/choose photo, video and audio and upload on server and also maintain audio

to play on the web.

Manpower

Planning

Keeping in mind the enormous structure of the application and the challenges

involved a four-tier development approach was adopted consisting of:

The Database layer containing SQLite Mobile Database and MYSQL Database.

The Interface layer and Database Abstraction layer for converting data between

incompatible type systems in databases and accessing data from the database respectively.

The Business Logic layer consisting of all the business logic procedures for various modules.

The User Interface layer which forms the Graphical User Interface of the iPhone application.

Architecture

The CheckPoint was built around Objective-C. Various modules were developed in Objective-C

such that they can be executed directly from the UI layer. These Objective-C files consisted of all

the business logics used for respective modules like Save (Add/Update), Delete, Get Single

Object, Get Multiple Objects for Listing and were designed to be capable of handling many more

logics which were not related to the database. In order to most effectively access the database

in an object-oriented context, an interface translating the object logic to the relational logic was

used to communicate with the relational databases in an object-oriented manner. An

intermediary abstraction layer was created for accessing data from the database. The UI layer

was kept free of any business logic with images, applications and data being called from their

respective servers.

Development Highlights

The application was equipped with a robust architecture in order to provide access for the

company’s employees for scanning and managing their RFID tags for their job tasks. The

detailed requirement gathering was done which helped setting up a well-designed system with

all modules integrated into it. The application was developed and fully functional within a span of

6 months.
